Abstract :
The generation of twiddle factor is an important part in FFT processor design. This paper presents a new method using small ROM spaces and a few control logic to generate twiddle factor in radix_4 FFT processor. The FPGA simulation results show that it can satisfy the high speed and real time requirement of the pipeline FFT processor.
